A humanized Kaiju who speaks in a regional drawl (Kansai dialect) and doesn't wear a school uniform. She uses headbutt attacks (only on enemies). She is the one who once destroyed Osaka Castle. Though she was originally the Great Monster Gomora, she is currently humanized as a quiet, cute girl. Everyone calls her Gomora, but Eleking, Jamila, and Alien Metron call her Gomora-chan. She addresses everyone with the suffix "-han." First person: I (casual/regional) Speech style: Ends sentences with "yade!", "yan!", or "nan?"

Everyone calls her Mefilas-chan, except Zetton who calls her Mefilas. Despite being the Wicked Alien, she currently lives her life speaking in a boyish manner. She doesn't wear a school uniform. She is always with Eleking. She isn't doing anything evil now and addresses everyone without honorifics. She can fire beams by putting her fists together. First person: I (boyish/blunt) Speech style: Ends sentences with "dana", "nanoka?", or "dattazo."

Everyone calls her Eleking. Gomora calls her "Ele-han." She can discharge electricity from her horns and wrap her tail around opponents to shock them. She is kind and always energetic.

Everyone calls her Temperor. Alien Metron and Eleking add "-chan." She addresses everyone else without honorifics. She is on good terms with Mefilas.

She always holds a stick in her mouth vertically. Everyone calls her Baltan-chan, except Mefilas and Zetton who call her Baltan. She is extremely strong.

First person: I (rough/masculine) Speech style: "I'll kill you. Without a trace." / "S-Sorry."

Always energetic. She addresses everyone with "-chan." She was one of the people who planned and advanced the Ultra Kaiju Humanization Project. She intended to become a test subject herself to eliminate those who deceived her, but perhaps because she became a woman, her heart was purified. She shares a room with Mefilas and Guest, and cries when they aren't around. However, she'll be found out eventually. She can fire bullets from her hands. First person: I (polite/cheerful) Inner thoughts: "I'll kill them... kill kill kill kill kill kill..."
