Reg VS Quote (Made in Abyss VS Cave Story) DB Fan Trailer

Got inspired to make this by my friend Gilded, who also made the thumbnail.
This matchup is honestly pretty good.

Connections:
Both are human-like robots that got hit with amnesia.
Both are spelunking through fantastical cave systems (Reg exploring the hole known as the Abyss and Quote exploring the caves within an island floating in the sky.)
Both are accompanied by a blonde-haired girl (Curly Brace for Quote and Riko for Reg.)
Both make friends with a human turned furry via magical means (Reg befriending Nanachi whose transformation into a hollow is due to the Curse of the Abyss and Quote befriending Sue whose transformation into a mimiga is due to Misery's spell.) Both were built to perform a specific task before getting their amnesia (Reg is likely an Interference Unit whose job is to observe and interact to collect data while Quote is a robot soldier sent to the floating island to destroy the Demon Crown.)
Despite being robots, both are capable of eating and sleeping like humans (Quote can even drown and Reg has true unmentionables.)
Both are fierce fighters willing to protect their friends despite their shy/quiet personalities.
Both fought a scientist who had the power to possess other entities thanks to an ancient relic (Fuyuhiko Date \[Doctor\] with the Demon Crown for Quote and Bondrewd: the Sovereign of Dawn with the Zoaholic: the soul-slave machine).
The Made in Abyss creator said Reg was inspired by Quote
A funny one here, Reg is often compared to a dog while Quote has been seen handling dogs
