HLIH

Currently a character not in the Mugen Dude yet, but will eventually make an appearance in Season 2

Star Summary
HLIH appears in Episode 9, she doesn't do jackshit until this episode happens, when she finally realizes ALX is destroying one of the universes, she teams up with anyone attempting to stop ALX at all cost to finally liberate the universe from ALX's disgusting fucking wrath, once and for all, and even helps NWFCSL to resurrect DVLRVNE.

Real Summary
RIOAU form

She is probably yet another horrible example of Deus Ex Machina, she appears out of nowhere to stop NWFCSL to prevent him resurrecting your best chad.

Despite there being destruction of the universe way before, she didn't even showed up RIGHT AFTER all of that happens, that just shows ALX just pulled this character out of his ass just to add more crappy characters to prevent actual good things from happening

Trivia

 * Her design is some touhou gril without their hat, really creative ALX...
 * She has two names, HLIH for The Mugen Dude Star, and RIOAU, for the regular Mugen Dude
