"Following his split with Blaze, Silver has grown stronger and has discovered his true power."
to me this means that ESP Silver is the Silver we know from 06 (and possibly generations)
while the Silver we saw in the Rivals games and other Spinoffs is a different Silver (this one: https://www.deviantart.com/nibroc-rock/art/Silver-The-Hedgehog-Legacy-Render-668974601)
it's funny to me how I made ESP Silver in a trunks outfit before a normal ESP Silver render: https://www.deviantart.com/nibroc-rock/art/What-if-ESP-Silver-as-Future-Trunks-649651151
