I avoid letting the DM's character steal the spotlight. As USEC has seen (as he is in that game), either accidentally or on purpose, I'll swap out my characters so they're not stealing spotlight.
The first one was Grot and was intended to be a joke character and a poke at bay12 as well as giving the party the healer it needed. He had a deep obsession with socks (think dwarves in DF going out of their way to get socks). At the time of his death, he had 36 pairs of socks. He was killed (unintentionally) by having a crit scored on him that instantly killed him by a character that dropped out, died by my DM magic of bad luck, and was revived by shadow magic.
The second was Thyra, the wood elf skald who's whole purpose was to get another character to stop complaining about a lack of roleplay in the middle of a mountain range. Needless to say, he completely ignored her. Her story is she's young for an elf and is tired of being considered that, so she sets out to try and show the elves of her kind she isn't a child anymore. She also forms a kind of bond with USEC's character hilariously enough through random rolls that were asked by other people. She abandons the party because of a fear of grotesque creatures, like undead, and leaves them behind... As they deal with an endless wave of enemies that get stronger and stronger everytime.
The current and third party member is Thoradin, the dwarf berserker. He's one of two people who fought another "joke" character (a space marine implemented into D&D because it can happen with the right gear, build, etc.) who turned insane because of 40k laws on Grey Knights (how they're immune to chaos, but because of that, he was attacked with shadow magic that, instead of taking him over, melded with him and became part of him. He literally is now in a state of in between life and death without being undead or vryloka, and it drives him batshit insane. He also revived another dead player character who is a slightly recurring enemy). He is missing an eye and is the only one who is slightly familiar with the dungeon they're in as it was his home before it was overrun with undead and necromancers. I'm not going to say much more about him since USEC is a character and I don't want to spew more plot spoilers that can be found out.
