The two do not meet in canon events. In Sonic Adventure 2, both are playable in multiplayer, but they cannot meet as Shadow is a runner while Tikal is a treasure hunter. Both are also playable in Sonic Runners, a now discontinued mobile app, but do not have any interactions. Shadow and Tikal also have counterparts in Sonic X and both Pre- and Post-Super Genesis Wave Archie comics, but their main reality versions in any of them are not shown to meet.
In the Light Mobius universe, King Shadow used Tikhaos, a merged form of Tikal and Chaos, to fight against the Freedom Fighters. Shadow fed it an excessive amount of Chaos energy, resulting in it losing control and wreaking havoc. Shadow's plan was eventually ruined as the Freedom Fighters defeated Tikhaos, while Shadow escaped the encounter.
Similarities and comparisons
- Both are prominently featured in past flashbacks of a Sonic Adventure game.
- Both were frozen in time for years until released at the beginning of a Sonic Adventure game.
- Both have known biological fathers in the games.
- Both are physically teenagers and do not age.
- Both have a connection to the Chaos Emeralds. Tikal was sealed inside the Master Emerald for 4,000 years, and is close to Chaos, who grows by absorbing Chaos Emeralds. Shadow was created for the purpose of collecting Chaos Emeralds and is naturally gifted with Chaos energy.
- Both also had experiences with some form of Chaos before them freezing in time. Tikal interacted with the real Chaos while Shadow fought multiple Artificial Chaos, an experiment gone wrong by Gerald Robotnik trying to recreate Chaos.
Shadikal is a fairly popular ship, but with many notable rival ships especially for Shadow. It can be shipped alongside Knuxouge as parallel to the popular ship combination of Shadouge and Knuxikal. Tikal's personality could remind Shadow of Maria, his closest friend, as both Tikal and Maria are peaceful, gentle and unwilling to fight. Shadow's personality is more violent, similarly to Tikal's father, but Shadow deeply cared about Maria while Pachamacac valued victory in war over his daughter. The ship also has a theme of light and dark to it, with Tikal representing light and Shadow representing dark.
On AO3, the pairing has seven fanworks, making it the most written ship for Tikal on the website. As the Sonic fandom is not very prominent on AO3 and based on the small number of fanworks for Tikal ships on the website, this might not reflect the actual popularity rankings of Tikal ships. It might be among the top 10 romantic ships for Shadow on the website, but this is not confirmed, and has the same number of fanworks as Shadow/Mephiles.
Shadikal has more popularity on DeviantArt, with over 1,000 results for the search "shadikal" and at least 11 favorites collections dedicated solely to the pairing. There is also a Shadikal fanclub with 230 members as of April 2019. A notable artist of the ship is Cylent-Nite, who has made multiple pictures of the pairing with hundreds of favorites each, and is also the founder of the ShadowXTikal fanclub. Another notable artist is XibalbaPiixan, co-founder of the ShadowXTikal fanclub.
The ship also has material on many other websites. On Tumblr, there are many posts with the Shadikal tag, usually featuring art of the two. On Wattpad, there are 8 stories using the Shadikal tag, although most of them are not centered around the ship. There are also multiple YouTube videos of the ship with hundreds or thousands of views, and a few with tens of thousands.
