Suggestion Box- Robots II (Patreon)

This month's theme will be Robots.

Suggest any character that is a full Robot type character (ie. Reploids from 'Mega Man X'). AI characters are also allowed (ie. Yui from 'Sword Art Online'. NOT AI generated characters, in case there's any confusion).
Original Characters are off limits.

These characters/series are also off limits for they won last time:
- Metis (Persona)
- Layer (Mega Man X)
- The Persona series will be locked out for this Suggestion Box.

I'll gather suggestions until 28th August 8pm BST, then put the characters into a poll.

(Notes:
- One request per Patron.
- Reference and scenario preferred.
- No duplicate characters.)
