Copperhead is a c/10 orthogonal spaceship discovered by 'zdr' on March 5, 2016.[1]
The first synthesis was proposed by Aidan F. Pierce on the day of discovery. An alternative synthesis utilising fumarole as a predecessor, presented by Tanner Jacobi an hour later, was much more efficient. After optimizations by Mark Niemiec and Chris Cain the total synthesis cost made 22 gliders.
The ship hauls a block behind it, which makes for interesting reactions involving other ships. Dean Hickerson built a sawtooth that uses copperhead's ability to turn a heavyweight spaceship into a loaf.[2] It can also eat gliders and middleweight spaceships cleanly from behind.
A copperhead gun was completed by Alexey Nigin on March 6, 2016.[3] A faster gun was constructed one day later.[4] The first copperhead to emerge from the ash of a soup appeared on April 4, 2016 in a D2_+2 haul submitted to Catagolue by Apple Bottom.[5]

Tagalong
On March 20, 2016 Simon Ekström found a tagalong with a large spark.[6] Tanner Jacobi noticed, that it can be attached to two other identical tagalongs, thus allowing for ships of arbitrary size.[7] Nico Brown built a puffer and a rake using copperheads with tagalongs to make a signal loop.[8]
