Instead of small pellets shot out of the sides like in the original, this one uses a more condensed version of Mega-Watt's electricity beam, and there are also variants for the attack if rotated at certain angles. It hovers much like the original, however, this one can hover MUCH higher than the original, the result being that this one can hover like the Egg Mobile from other Sonic titles. It still retains many of its classic traits, but it actually has an ENTIRELY new attack set. This is pretty much a long-awaited overhaul of the Submarine Mobile from the Game Gear, as mentioned. So, with that being said, the final product of the transfer awaits! Now, the cockpit for the Spider-Mobile is INVERTED, and this is why i didn't see the similarity before actually looking between the two images. See the cockpit? It reminded me of Game Gear's Sonic 1 Bridge Zone boss, as shown in the second attachment: I realized something while playing Sonic Mania that influenced me to do this certain edit, and that's thanks to the Spider-Mobile from Flying Battery Zone Act 2. Since i don't do well making my own sprites, i decided to edit sprites instead.
