*Dr Farnsworth walks in* GOOD NEWS EVERYONE!
I'll let the pictures and their captions speak volumes, but first I should note... Sparrowmon and Axemon both found, defeated, and Digifused with.
The Flying Hero, Shoutmon X5. This is the strongest possible Digifusion on the Shoutmon Red Mini... on the other hand, it is NOT Shoutmon's strongest form by a longshot. That came after the Minis had their run, and came in the form of Shoutmon X7.
The Immortal Champion, AxeKnightmon. Again, this is the strongest possible Digifusion, but in this case it is for the SkullKnightmon Black Mini. There are three stronger forms for SkullKnightmon, but these were mostly one time things. Super AxeKnightmon (AxeKnightmon + SkullGreymon + SkullSatamon) was only used to escape from one battle and was never seen again, MusoKnightmon (AxeKnightmon + Tuwarmon) was a temporary powerup used only once or twice, and his Digifusion with Bagramon... that didn't work out in AxeKnightmon's favor at all, so that one definitely doesn't count as one of SkullKnightmon's forms.
As for the clearer pictures? I misplaced the USB cable for my usual camera (The one I used here) before the hatch began, but relocated it in time to take these, as well as the pics I'll take after these.
While Shoutmon X5 and AxeKnightmon cannot go any higher, this run is by no means over. Eventually, the Digifusions will undo themselves and they will revert to Shoutmon and SkullKnightmon. At that point, I will be going after the Digifusions I skipped so you folks get to see all nine raisable Digimon on both versions.
