Seven

Personality:   Seven is a person who likes jokes and tries to be funny. However, these jokes seem to usually fall flat, and no one seems to like them. Seven used to only care about being in the spotlight, according to Eight. With them also previously being a whiny person, due to them crying over not being in the sub count (and therefore not being in the spotlight) in "Thanks for 600,000 subscribers!". As well as being selfish, they are stubborn and uncaring to an extent, shown by them being unwilling to help the other numbers catch Six and to leave the sub count so Eight can take their place in "Thanks for 800,000 subscribers!". They seem to be growing somewhat kinder, as they stated they don't hold grudges and was rather nice greeting everyone.
