Event Horizon MK4 competed at the September 30th event and did very well. The bot plowed through its first two matches with one-hit KOs before going up against The Loophole-style robot, Booty Brigade. The fight ended with the battery unplugging in Event Horizon, but other than that, there was no structural damage to the robot. After being knocked out of the competition, Event Horizon went up against Chainsaw Kitty in a grudge match. The fight led to Event Horizon ripping all the way through the first polycarbonate cage wall twice and damaging the second once—a first-ever in the 3lb weight class at NHRL. The match ended with the power wire to the receiver getting unplugged, but again, there was no structural damage to the robot.
====== Notable Changes: ======
* Removed two unnecessary T-nuts from the center of the bot
* Upgraded to an AR600 blade
* Reduced the number of blade teeth from two to one
* Increased the length of the tooth from 25mm to 45mm
* Added a shield to one side of the blade to defend against horizontal weapons
* Upgraded to roller bearings for horizontal constraint
* Switched to dowels instead of screws to hold the vertical constraint bearings for repair speed
==== '''MK3:''' ====

Event Horizon MK3 competed at the August 12th, 2023 event and did incredibly well. The bot lost its first match due to an internal technical issue, but won the next three before being struck down by Spartan. Spartan's blade managed to pass below the blade of Event Horizon and damage a weapon motor causing the entire weapon to stop spinning. Event Horizon was otherwise unscathed but the loss of its weapon led to Spartan taking the judge's decision.
====== Notable Changes: ======
* Changed cleat geometry so the spikes point outward radially
* Changed cleat material to higher carbon spring steel so they hold an edge
* Made cleats thinner to improve bite into the floor
* Changed chassis material to TPU for better print reliability and ductility
* Added T-nuts to the center of the chassis
==== '''MK2:''' ====

Event Horizon MK2 competed at the May 6th, 2023 event and did much better than before. Event Horizon succeeded in winning its first qualifying match and first bracket match but was unfortunately pitted against Eruption in its second bracket match, where it lost by a split judge's decision.
====== Notable Changes: ======
* Added an additional weapon motor to improve torque and reduce the time required to spin up
* Changed from gluing O-rings directly to the motor can to using a 3D printed polycarbonate hub to hold the O-rings in place
* Switched to low carbon steel cleats for better grip, reduced weight, smaller formfactor, and customizable diameter
* Chassis is moisture treated this time as it drastically improves the durability of CoPA 3D prints
* Chassis halves are now interchangeable to reduce the number of spares required
* Total thickness of the chassis was reduced by 10.85mm
* Chassis is held together with T-nuts and threaded rods rather then recessed nuts and blots
==== '''MK1:''' ====

Event Horizon MK1 competed at the March 18th, 2023 event with mixed success. While the general design showed promise, Event Horizon lost both qualifying matches and was eliminated.
====== Features: ======
* Invertible design
* 3D printed CoPA chassis
* MegaSpark brushless gear motors for drive
* 2" 40A BaneBots wheels
* Weapon is driven by 3 2600Kv motors
* 1/4in thick 250mm diameter AR500 blade with 25mm bite
