It looks like PotP Optimus didn't get a ton of third party upgrade love. Far less than most Prime Wars Leaders anyway. And some or most of PotP Optimus' upgrades should work on Star Convoy. I went a bit nuts with TF Safari's discounted Selects Star Convoy. I always wanted an official Star Convoy but had doubts about the PotP Optimus mold enough to pass on it. So I got an array of companion pieces coming in. The first is obvious and official: WST Hot Rod. Star Convoy had a MM Hot Rod. This guy should get one too. Second: until I saw TF Safari's deal, I was put off my PotP Optimus' stickers already and even more put off by Star Convoy having stickers that have to be self-applied. If I'm going to self-apply, I want something better. So I picked up a set of Ocean Decals PotP decals for around $12. I've been impressed with their decals. They're practically tampos and if sealed with a brushed on clear coat, they essentially are. But Ocean's decals have a bonus feature: glow in the dark trailer stripes. Parts of the set won't fit or make sense but that gets me trailer stripes that shouldn't peel or add unsightly sticker bulk. I of course snagged one of Shockwave's Labs upgrade kits for the leg fillers. Eager to sed how they work out. Finally, since Deep Space Alliance is no longer with us, I picked up some bootlegs of his PotP ankle stablizers in black being well aware of PotP Optimus' floppy ankles which I have heard are worse on Star Convoy. I thought for sure he'd have a hand upgrade kit useable from somewhere like literally every other modern leader class I can think of except Astrotrain. Even the ones who didn't explicitly like Black Shadow/Sky Shadow have hands shared with Overlord and Dai Atlas who DO have hand upgrade kits you could put on Black Shadow/Sky Shadow. Not owning Leader PotP OP, I'm guessing his hands can't be removed? If he has compatible pegs with Rodimus, I'm getting one of those kits for articulated Rodimus Prime hands. Yes, I spend $35 upgrading a so-so mold IMHO but TF Safari was selling it for $40 less than typical eBay prices right now and sprucing up a figure is both something I enjoy and a way to pass time during the Covid crisis. And Super Megatron is drop dead sexy (and made from a mold I like with virtually all of that mold's flaws tooled out) and needs a worthy adversary on the shelf.
