The battle takes place on the Great Fox. Unlike the Corneria stage, the battle is fought on the front view of the ship, in contrast to the side view. Characters can fight on either 4 wings of the ship, and somewhat on the tailpiece in the center of the stage. This tailpiece is also a hazard that makes it hard to go to the other side. The top two wings of the ship slope inwards while the bottom two wings slope outwards. Items tend to roll off the two bottom wings of the ship.
Every now and then, an Arwing or Wolfen will appear and start firing at the ship then will fly off. Any character that gets hit by the shots will take damage. Also, when the ship flies into the cave, sometimes characters will bounce back onto the stage when smacked upwards or towards the sides due to the top, left, and right blast lines being obstructed by the cave itself, which might save one from getting KO'd.
Ω form and Battlefield form
In Super Smash Bros. Ultimate, the Ω form and Battlefield form are set on a slightly redesigned version of Corneria's Ω form from Super Smash Bros. for Nintendo 3DS; however, it is resized and reshaped to match Final Destination and Battlefield, respectively. The three soft platforms of the Battlefield form are metallic and are unique to this form. Arwing and Wolfen do not interact with the stages.
The planet Venom first appeared in Star Fox (Starwing in the PAL region) and has appeared in numerous Star Fox titles since; however, this stage is based on its appearance as the last level of Star Fox 64 (Lylat Wars in the PAL region), and is where the final boss, Andross, is fought. In the Star Fox games, Venom is a barren, desolate planet full of steep cliffs and deep chasms of rock that the Star Fox team must maneuver through to reach Andross, who was exiled to the deadly planet due to his crimes against Corneria. However, unlike as seen in this stage, Venom does not have volcanic activity.
In Star Fox 64, Star Fox encountered various dangers on Venom, such as holes in the cliffsides and in the ground where enemy aircraft emerged to attack, giant, jagged rocks that emerged from the ground as soon as they got close, and a barrage of stone pillars that appeared to block their path. In the background of this stage, references to these obstacles can be seen.
The Great Fox, Star Fox's mobile headquarters, acts as the main platform of the stage; however, at no point in Star Fox 64 does the Great Fox fly over Venom's surface. Also in this stage are Arwings and Wolfen, flown by Star Fox and Star Wolf, respectively, that occasionally appear to act as small platforms. All three aircraft are based on their appearances in Star Fox 64, and the Arwings apparently have one Laser Upgrade, as they fire two lasers at once as opposed to the standard one.
Venom is banned in tournaments, primarily due to the fin in the center of the stage, which can easily cause infinite combos; the bottom wings also promote camping, and the blastlines are considered to be too close to the stage.
