@LoveNotWar for the prompt, which has been tweaked somewhat.
It turns out you actually can make a decent mech with Ideogram 2a Turbo, but it requires a different approach from Flux models. I2aT has the same bias towards bulky western mech designs as Google Imagen, so you have to use a preset and then use the keywords for a different preset in your prompt. This mech also leans heavily into the tokusatsu style, which I'll take into account going forward.
The cylinders on the wings are missile pods, while the ETC arm cannon fires 45mm plasma shells. The shells are covered with a pyrophoric coating that begins burning as soon as the shell is fired due to friction with the atmosphere, and as the coating burns, it forms a plasma sheath around the shell that blunts air resistance, improving the shell's terminal ballistics. The 26-foot-tall Shogun's leg armor is much heavier than most mecha to counter tank shells.
