isn't this alreayd on here?

Yes, but it wasn't approved. It was bigger, too.

You can use http://danbooru.iqdb.hanyuu.net/ to check when you think there's a duplicate.

1: What, no Gurren Lagann?

2: If you really wanna be nerdy with this; assume the electron count on the periodic table is increased proportionally with the size of each robot. Re-order table based on that.

Si is Silicon, and Sizzler Black.

C, Carbon, Cybuster

Li, Lithium, I THINK that may be Linebarrel...

N, Nitrogen, Nu Gundam

W, Tungsten, Warsman

Cr, Chromium, Crisis Suit

Pt, Platinum, Personal Trooper (Gespenst to be exact)

U, Uranium, Urbanmech!

Bk, Berkelium, Black Getter.

Es, Einsteinium, Escaflowne.

Pu, Plutonium, ....I think that's Elpe Puru's Quebley.

Am, Americium, Airman.

Zr, Zirconium, Zeorymer.

Tl, Thalium, Tallgeese

Sb, Antimony, Sazabi

Cs, Cesium, Crossbone Gundam

Tc, Technetium, Tachikoma

Db, Dubnium, Diebuster.

Ra, Radium, RaXephon

Au, Gold, Anubis

P, Phosphorous, Pluto.

Ar, Argon, Arbalest

Dy, Dysporium, Daizengar.

At, Astatine, Atlas

Al, Aluminum, Alteisen.

Hs, Hassium, Hyaku Shiki

Fr, Francium, Fafner

V, Vanadium, Valkyrie

Rh, Rhodium, Rai-oh. (Or Dai-Rai-Oh.)

That's all the ones I can pick out that didn't have notes when I started writing.

Oh, Pm is Promethium, not Plutonium, Rb is Rubidium, and is obviously a Ball, Ah! Po is Polonium, and is Prometheus, also known as Robo from Chrono Trigger. Hg is Mercury and Hygogg.

Rf is the main golem from Break Blade - Dirfringe.
La is the Suzuku's unit from Code Geass - Lancelot.
Pa is from Zeta Gundam - Palace Athene
Cr is from Warhammer 40K Tau Army - Crisis Battlesuit

No Megas either. I am dissapoint.

There's no place for Gurren Lagann, and the only place for Megas would be Mazinger's spot.

No Gold Lightan for gold? Bah.

Disappointed at lack of Megas. I think Mg would work better as a Metal Gear, but whatever.

Ca- Mad Cat (Timber Wolf) from Battletech
Cr- Crisis Suit from Warhammer 40k
At- Atlas from Battletech
Ce- Compatible Kaiser from SRW: OGG (not 100% on this one)
Yb- Ialdabaoth from SRW: Alpha 3/OGG
U- Urban Mech from Battletech
Es- Escaflowne, title mech of the same show

Any approval in sight?

Ne looks almost like the Neuve Zeile from Gundam 0083.
