I find the assertion of 'city busting' funny. On my home forum, Corban was listed as mild powers, which was gauged by 'blockbusting'. As in a maximum powered attack should do no more than level/ destroy a city block. He specifically could not, and I don't ever remember destroying a city or tanking a nuke. To let off a city sized attack would be impossible for Corban without it being some story element, or a stupidly high tier fight where all semblance of restraint is a foreign concept.

Enki: Gundams don't really have a general size as I recall. It depends on the timeline (UC, GC?). Some are seventy meters tall while others are like 20.
