(I think the one on the left in the last image is a unique Seeker) There are some other designs too, I think, but these are the ones readily noticeable. Concept art:
I do like how Starscream's stands out overall but I like the implementation of the gas mask for the rest.
Blitzwing of course. The Cybertronian body has some cool details but the real jet parts on Blitzwing and his overall chest curvature is just cooler.
The BB Seeker design is probably one of my all-time favourite TF designs. Brilliantly modern and detailed yet classic and traditional. I think Blitzwing is my favourite because it is the most cohesive. The Cybertronian version is fine but it's obviously got Earth jet kibble on it.
Blitzwing is probably the best looking imo just because of how well the earth kibble informs the robot mode. I actually don't think Thrust's design went far enough for two reasons: The fact that the conehead isn't technically a conehead, and the fact that Armada Thrust wasn't actually green. He was mostly grey and cyan accented with a much darker olive green central portion of his torso. Not even all the torso, just that central strip.
At the same time, they wanted him to match the other seekers. It's an homage, not a literal 1:1. Like how Shatter was an homage to Nightbird. Just because you allude to something doesn't mean you have to copy it.
I genuinely love the "conehead hood" design the Bee movie did. It evokes the silhouette of the coneheads without looking fucking stupid.
I really like them all on their own respective right, although I must say I'm not a fan of Thrust at all tbh. I don't see the hype but that's just me. Since I have to choose my favorite I gotta vote for Blitzwing. Idk how to explain it but he's just the perfect mix of earth and cybertronian modes put together. After him I really like Skywarp
starscream cybertronian,in terms of toys is cyber factory star storm which captures it better than ss
im surprised they havent rapidy started pumping out recolors of starscream, blitzwing, and thrust figures as multiple other seekers yet
They're actually gonna start to with Thundercracker, Skywarp, Redwing and Sunstorm. I wouldn't be surprised if we get non-movie deco's I could see them doing other conehead and maybe a G1 Thrust colored Seeker (maybe with a new name).
