If he crosses over towards the corner, I'll usually push block to get favorable map control. Otherwise a high low block takes away most of his options unless he uses air sparks for an additional overhead, but I believe that is punishable on block.
If you make a hard read, back dash, d2 and sometimes b1 or upstars with Redhood can be good options. If it's on reaction, just block or push block.
Edit: you can also use some mb interactables to blow him up depending on the stage/ positioning
