The time/clock/skull motif is pretty consistent for him in all universes-- particularly with regards to running out of time.
Roses and wings throughout bc he is an edgelord (and a literary sap at heart)
And a triskelion on his neck-- a Celtic symbol of action, cycles, progress, revolution, and competition. He hates stagnation and futility (though he ends up rather nihilistic), always keen on productivity and progression.

He hates the nickname 'Cal' for some reason (likely because it's already his upperclassman's), but he's used to Cald, Scalder (for his sharp tongue), and O'Mannagan (because he's insanely hyper-competitive at sports).
