Welder

Welder is a Lunar League player on the Thunderbolts team and is described as a gentle giant, as evidenced by his huge body. Welder is a wise bot, and he is very reasonable. He is an old bot, and he goes to the Fraternity of Season Silicon Intelligence Legionnaires. Because of his age, he can't think through things as fast as the newer bots, like in episode 3, when Welder was looking for information on Squeaker. He is able to search his own memory files, but renders him inert for a while. While he was searching for a memory file relating to Squeaker, he was inert for a long period of time, due to being stuck in an infinite memory loop.

Appearance
He appears to be large in size, as he is a gentle giant. He also appears to have an old processor because of his age, as said in the first episode. Like all Thunderbolts members, he has blue eyes and the yellow and blue uniform for the Thunderbolts with it's logo imprinted on it.

Personality
He shows to act like an wise elderly robot, as he shows that he likes music no one remembers, a reference to old people liking old music. He was shown to get cranky once when Blip and Bolts did a signature move (and fans housewarmed his house after). He ended up in jail framed for holding the wild party. When a prisoner mentioned about it, he got so mad, he blasted off back to his apartment and kicked Blip and Bolts out of his house (consequently smashing his figurines).

Relationships with other characters
Blip- Welder tends to talk to Blip as Blip is part of his team and his friend.
