Ugliest mecha I've ever seen....well, almost.
Also, power is somewhat irrelevant to quality, isn't it?
I love the way Jehuty looks. It's sleek and badass.
Orbital Frames are made out of Metatron, with comes from Mars, so Jehuty and Anubis are the two most powerful Orbital Frames. Jehuty also has an array of weapons like homing lasers, burst attacks, homing missiles, WISPs, Halbred, a Vector cannon and most importantly the Zero Shift function. (When Jehuty upgrades to Jehuty version. 2 it gains Zero Shift and has all these weapons). Anubis is Jehuty's twin frame and is the most powerful C-type Orbital Frame. Zero shift gives the frame the ability to teleport.
Both Orbital Frames also have a vector trap with allows them to store weapons and such. So in terms of power, agility and firepower, Jehuty would destroy a Gundam rather quickly. Even the beam spamming SEED suits wouldn't be able to survive repeated homing laser attacks and a Halberd to the cockpit.
So power is affected by the quality of the Frame. Orbital Frame Jehuty can also repair it's self by coming in contact with Metatron, as you may already know.
