Both Michael and Gabriel.

His favorite olvar form is that of a falcon. Tends to stay towards bird forms and as an elf usually Vanyar or a surprisingly short Noldor with light brown hair and pale blue eyes.

Best friend among the Maiar outside of his and Ilmarë’s people are Salmar and Arien (and he has a fondness for Tilion but only in smaller doses.)

He is the dutiful son (though okay, only the earliest version of the legendarium had Eönwë as Manwë and Varda’s son) and loving supportive brother. His anger is not the long-held poisonous rage of Ilmarë, but the sad disappointment that Manwë has, that Melkor and all his followers (and this is the same sin of Fëanor) could have been so much better than they were, if only they saw that their talents and essence were geared towards collaborating with others, that they would have been so much greater if only they accepted that other people could contribute and have worth and not to be a control freak jealous that anyone else had a decent idea. He thinks Sauron’s mocking of Eönwë for never aspiring to be more than Manwë’s errand boy is delightfully ironic – oh, and that his sister’s ex is a weak coward. Eönwë is pretty contemptuous of cravens and traitors – and he thinks Eärendil is the best and bravest and totally bffs and Eönwë joins Eärendil on Void voyages sometimes.

(Eönwë’s opinion of Sauron in one word: loser.)

He and Tulkas get into arguments constantly because Tulkas has raw strength and can wrestle anything into submission once he gets ahold, but since Eönwë canon-wise is mightiest of all with all arms- that means Eönwë is best with swords, bows, whatever weapon you pick- and the leader of the armies- thus he’s every top-tier general rolled into one. Tulkas’s lack of tactics drives him up the wall. And when the War of Wrath starts- Eönwë is the one to make sure the Vanyar and Noldor under Finarfin have the best practical and efficient weapons possible – which because they aren’t making these ‘in secret’ and have the experts helping, are a lot better and more uniform. Frankly, I’m half tempted to put some gunpowder weapons here. (Saruman had to know of it from somewhere…) Eönwë probably admires Fingolfin, though I’m undecided  if he officially likes him more than Finarfin.
