I work in game testing. Its boring as fuck but I get early access to games like Pokemon. With Terrahowl having been revealed, I can confirm the starters get day and night evolutions too. THESE ARE NOT FORMS LIKE TERRAHOWL HOWEVER. They're split evolutions.

Im not the best at drawing but here's what they look like in the Pokedex icons.

Anything else you guys want me to draw or confirm?
