The above picture is of a Tasmanian Devil, which is a marsupial that has a niche within that ecology akin to a hyena on the African Plains. Such was part of creation. So were the angels.
The orthodox position is to say that Angels are something we are not and something that it is not helpful for us to know much about. The Schoolmaster puts it this way:
I answer that, There must be some incorporeal creatures. For what is principally intended by God in creatures is good, and this consists in assimilation to God Himself. And the perfect assimilation of an effect to a cause is accomplished when the effect imitates the cause according to that whereby the cause produces the effect; as heat makes heat. Now, God produces the creature by His intellect and will (I:14:8; I:19:4). Hence the perfection of the universe requires that there should be intellectual creatures. Now intelligence cannot be the action of a body, nor of any corporeal faculty; for every body is limited to "here" and "now." Hence the perfection of the universe requires the existence of an incorporeal creature.
The ancients, however, not properly realizing the force of intelligence, and failing to make a proper distinction between sense and intellect, thought that nothing existed in the world but what could be apprehended by sense and imagination. And because bodies alone fall under imagination, they supposed that no being existed except bodies, as the Philosopher observes (Phys. iv, text 52,57). Thence came the error of the Sadducees, who said there was no spirit (Acts 23:8).
But the very fact that intellect is above sense is a reasonable proof that there are some incorporeal things comprehensible by the intellect alone.

Calvin is a bit more explicit. What we are given in the word is not complete but is what is useful, and speculating on the occult does not help us.
3. But before I begin to treat more fully of the nature of man (chap. 15 and B. 2 c. 1), it will be proper to say something of angels. For although Moses, in accommodation to the ignorance of the generality of men, does not in the history of the creation make mention of any other works of God than those which meet our eye, yet, seeing he afterwards introduces angels as the ministers of God, we easily infer that he for whom they do service is their Creator. Hence, though Moses, speaking in popular language, did not at the very commencement enumerate the angels among the creatures of God, nothing prevents us from treating distinctly and explicitly of what is delivered by Scripture concerning them in other places. For if we desire to know God by his works, we surely cannot overlook this noble and illustrious specimen. We may add that this branch of doctrine is very necessary for the refutation of numerous errors. The minds of many are so struck with the excellence of angelic natures, that they would think them insulted in being subjected to the authority of God, and so made subordinate. Hence a fancied divinity has been assigned them. Manes, too, has arisen with his sect, fabricating to himself two principles--God and the devil, attributing the origin of good things to God, but assigning all bad natures to the devil as their author. Were this delirium to take possession of our minds, God would be denied his glory in the creation of the world. For, seeing there is nothing more peculiar to God than eternity and aujtousiva, i.e. self-existence, or existence of himself, if I may so speak, do not those who attribute it to the devil in some degree invest him with the honour of divinity? And where is the omnipotence of God, if the devil has the power of executing whatever he pleases against the will, and notwithstanding of the opposition of God? But the only good ground which the Manichees have--viz. that it were impious to ascribe the creation of any thing bad to a good God, militates in no degree against the orthodox faith, since it is not admitted that there is any thing naturally bad throughout the universe; the depravity and wickedness whether of man or of the devil, and the sins thence resulting, being not from nature, but from the corruption of nature; nor, at first, did anything whatever exist that did not exhibit some manifestation of the divine wisdom and justice. To obviate such perverse imaginations, we must raise our minds higher than our eyes can penetrate. It was probably with this view that the Nicene Creed, in calling God the creator of all things, makes express mention of things invisible. My care, however, must be to keep within the bounds which piety prescribes, lest by indulging in speculations beyond my reach, I bewilder the reader, and lead him away from the simplicity of the faith. And since the Holy Spirit always instructs us in what is useful, but altogether omits, or only touches cursorily on matters which tend little to edification, of all such matters, it certainly is our duty to remain in willing ignorance.
4. Angels being the ministers appointed to execute the commands of God, must, of course, be admitted to be his creatures, but to stir up questions concerning the time or order in which they were created (see Lombard, lib. 2 dist. 2, sqq.), bespeaks more perverseness than industry. Moses relates that the heavens and the earth were finished, with all their host; what avails it anxiously to inquire at what time other more hidden celestial hosts than the stars and planets also began to be? Not to dwell on this, let us here remember that on the whole subject of religion one rule of modesty and soberness is to be observed, and it is this, in obscure matters not to speak or think, or even long to know, more than the Word of God has delivered. A second rule is, that in reading the Scriptures we should constantly direct our inquiries and meditations to those things which tend to edification, not indulge in curiosity, or in studying things of no use. And since the Lord has been pleased to instruct us, not in frivolous questions, but in solid piety, in the fear of his name, in true faith, and the duties of holiness, let us rest satisfied with such knowledge. Wherefore, if we would be duly wise, we must renounce those vain babblings of idle men, concerning the nature, ranks, and number of angels, without any authority from the Word of God. I know that many fasten on these topics more eagerly, and take greater pleasure in them than in those relating to daily practice. But if we decline not to be the disciples of Christ, let us not decline to follow the method which he has prescribed. In this way, being contented with him for our master, we will not only refrain from, but even feel averse to, superfluous speculations which he discourages. None can deny that Dionysus (whoever he may have been) has many shrewd and subtle disquisitions in his Celestial Hierarchy, but on looking at them more closely, every one must see that they are merely idle talk. The duty of a Theologian, however, is not to tickle the ear, but confirm the conscience, by teaching what is true, certain, and useful. When you read the work of Dionysus, you would think that the man had come down from heaven, and was relating, not what he had learned, but what he had actually seen. Paul, however, though he was carried to the third heaven, so far from delivering any thing of the kind, positively declares, that it was not lawful for man to speak the secrets which he had seen. Bidding adieu, therefore, to that nugatory wisdom, let us endeavour to ascertain from the simple doctrine of Scripture what it is the Lord's pleasure that we should know concerning angels.
I have always been somewhat creeped out by the popular image of the angel with wings and blonde hair, and the books in which they are fighting, or the statues people give as if they give protection. Our protection is from God, and the angels say that they are his servants.
Better to say that we all have a place in creation. We have a role. Marsupials included.
