Vaike is a self-proclaimed rival of Chrom and a member of the Shepherds. He aspires to become "a warrior among warriors", and is always eager to seek challengers to prove his might.

Vaike possesses an abnormally inflated ego, a fact that is bolstered by him constantly referring to himself as Teach (俺様 Ore-sama, lit. The Great Me in the Japanese version). Often times, this ego of his is unjustified, as its constant overclouding of his judgment sees him incapable of comprehending why things never quite go the way that he envisions. Such instances include him getting confused when Sullyreceives more gifts from women than he does, alongside Tharja obsessing over Robin and not him. 

Clearly befitting the archetypal mold of the man in possession of more brawn than brains, Vaike seeks to fulfill the purpose of strengthening himself and thereafter becoming the greatest fighter in the entire world. This ambition of his is, however, offset by his forgetfulness, being considered the best at misplacing things in the army, as evident from his misplacing his weapon in Chapter 2, alongside failing to remember to relay vital information to other members of the army.
